Definitly a solution. Unlike most comments (until now (11-11-2014 22:58)) I really think this contributes to a better total sustainable power generation. As Johannes Annema (incorrectly) stated, that the greenhouse gasses will not reduce, I figured this has to do with the current CO2 exhaust rights-system. Recently the Dutch CBS also made a huge mistake calculating with these CO2 rights.

By building these near-shore farms I think we can suppress the costs to build the farms and have more sustainable power feed-in into the net by TenneT. This way, coal and gas fired powerplants can reduce their operating time and THUS the windfarms can reduce the greenhouse gas emissions. (there you go Johannes Annema).
